Pronator Syndrome

• Condition: Compression of the median nerve in the forearm, distinct from carpal tunnel syndrome.
• Description: This condition occurs when the median nerve is squeezed as it passes between the two heads of the pronator teres muscle in the forearm or near the elbow.
• Symptoms: Aching pain in the upper forearm, numbness in the thumb, index, and middle fingers, and weakness when pinching or gripping objects.
• Causes: Repetitive forearm rotation, forceful gripping, or direct pressure trauma to the forearm muscle.
• Risk Factors: Occupations or hobbies involving heavy tool use, frequent screwdriver twisting, assembly line work, or extensive racquet sports.
• Diagnosis: Evaluated through a physical examination, specialized clinical compression tests, and often confirmed with electromyography (EMG) and nerve conduction studies.
• Treatment: Initial management includes activity modification, non-steroidal anti-inflammatory drugs (NSAIDs), physical therapy, and splinting. Persistent or severe cases may require surgical decompression.
